Abstract

Design: We report the case of an incidental pituitary mass discovered in the context of bilateral cavernous sinus thrombosis due to a bacterial pansinusitis.

Conclusions: Magnetic resonance imaging features of the pituitary lesion, together with transient central hypogonadism and total regression of the mass after anticoagulation and antimicrobial therapy, suggest that this lesion is a pituitary oedema of vascular mechanism. Other possible causes of pituitary mass in such a situation are also discussed.
